Hmm. That is an odd one from a quick thought...

However, IF you are planning on growing and adding OSSes/OSTs, this is 
not a bad way to get started and used to how everything works. It is 
basically a single stripe storage.

If you are not planning on growing, I would lean towards gluster on 2 
boxes. I do that often, actually. A single MDS/OSS has zero redundancy, 
unless something is being done at harware level and that would help in 
availability.
NFS is quite viable too, but you would be splitting the available 
storage on 2 boxes.
